Q1:What is the function of rolling bearing cage?

A:The cage (also known as cage and isolator) evenly separates the rolling elements in the bearing from each other, so that each rolling element can roll normally between the inner ring and the outer ring. In addition, the cage has the functions of guiding the movement of the rolling elements, improving the internal lubrication conditions of the bearing, and preventing the rolling elements from falling off.
The function of the cage is:

1. Guide and drive the rolling body to roll on the correct raceway;
2. The cage separates the rolling elements at equal distances and distributes them evenly on the circumference of the raceway to prevent the rolling elements from colliding and rubbing against each other during work;
3. In separable bearings, the rolling elements are combined with a ring to prevent the rolling elements from falling off.

Q2:What is the main function of the flange in bearing assembly and mechanical assembly?

A:The main function of the flange is to connect the pipes. Most of the large-diameter pipes used in the equipment, such as gas, hydraulic oil, and water, are connected by flanges. It is characterized by firm connection, good sealing, simple manufacture and easy operation. Most of them are used in the assembly of bearings for the assembly of tapered roller bearings. The outer ring of tapered roller bearings is installed on the flange. The gap can be adjusted with metal pads, and the installation is very convenient.

Q3:Uses of rod ends

The rod end joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can bear a large load. According to the different types and structures of the rod end joint bearing, it can bear radial load, axial load or combined load in both radial and axial directions. Rod end joint bearings are generally used for low-speed swing motion, and can also be used for tilt motion within a certain angle range. According to its different types and structures, it can bear radial load, axial load or combined load in both radial and axial directions. Rod ends are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automobile shock absorbers, water conservancy machinery and other industries.

Q4:What are the uses and advantages of spiral roller bearings?

The rolling system of spiral roller bearings adopts spiral rollers wound with steel strips. Therefore, it is called a spiral roller bearing. This type of bearing has large elasticity and radial clearance, can withstand large impact radial loads, cannot bear axial loads, and has a low limit speed. It is only suitable for parts with low rotation accuracy and often with large impact loads. When the bearing is installed, the axis of the inner ring and the axis of the outer ring are allowed to have an inclination of 0.5°. Due to the elastic deformation of this type of bearing, the accuracy cannot be guaranteed in the work, so the accuracy of the spiral roller bearing is only one of the ordinary grades, and there is no other precision grade.
